Specification of Letters Patent.

Patented Nev. a, rem.

To all whom it may concern.v

Be it known that I, WILLIAM E. COOKE, a citizen of the United States,and a resident of Shellmound, in the county of Lelore and State ofMississippi, have invented a new and Improved Grin, of which thefollowing is a full, clear, and exact description.

The invention is an improvement in gins, and has in view an air blastgin which is arranged and constructed to first gather the dust, leaves,trash and motes which may remain in or about the cotton fiber after theAseed is removed, and discharge the same by means of a division or partof the blast to the outside of the building or other remote point,'and,secondly, afterward remove the cotton liber from the saws by means ofanother division or the remaining portion of the air blast, anddischarge this ber by the blast into the condenser.

'The invention further contemplates a whipping-board for threshing thedust from the cotton at or near the point at which the leaves, trash and.motes are removed, adjustable to and from the gin saws, adapting it tolong or short staple cotton, as desired.

Reference is to be had to the accompanying drawings forming a part ofthis speciication, in which similar characters of reference indicatecorresponding parts in both views.

Figure 1 is a central vertical section through that portion of the ginembodying my improvements; and Fig. 2 is a crosssection of the samesubstantially on the line 2 2 of Fig. 1, with the gearing and otheractuating mechanism omitted.

The gin comprises asuitable frame-supported casing 5, having at theforward side thereof the gin saws 6, to which the cotton is fed.Adjoining the upper portion of the saw is a refuse chamber 7 forreceiving andv collecting the dust, as well as the leaves, trash andmotes, which the cotton at this point contains. The rear wall of thechamber is formed by a downwardly and forwardly inclined guide-board 8,against which the trash and motes are thrown from the gin saws bycentrifugal force, the lower edge of the guide-board terminating at ornear the level of the saw axis and adjoining the upper wall of anupwardly and rearwardly inclined chute 9. which discharges into a pipe.or duct 10, leading to the outyranged at the outside.

side of the building 0r other point of aischarge.

Leading into the rear of the gin casing .under the chute 9, from theblower, is an airinlet duct or pipe 11, at the front of which and spaceda substantial distance therefrom 1s a downwardly and forwardly inclineddelector 12, extending from the I lower wall of the chute 9, thedeflector terminating a substantial distance from the upper wall of achute 13, which leads to the condenser, the upper wall of the chute 13at its inner end passing relatively close to the gin saw 6, leaving acontracted passage 14 therebetween, for the lint adhering to the sawteeth. Between this portion of the chute 13 and the inner portion of thechute 9 is interposed a dividing-block 15, forming at its upper side, inconnection with the lower wall of the chute 9, a contracted air conduitor nozzle 16, and its lower side, in connection with the extension ofthe chute 13, a contracted air conduit or nozzle 17, the air conduit 16being directed up the chute 9 and the air conduit 17 leading into thecontracted passage 14 to the chute 13. The upper face of thedividing-block 15 opposite the mouth of the chute 9 is flattened andforms a seat for a whipping-board 18, the latter being preferably ofwedge-form, with t-he sharp edge extending toward the saws, the board atits opposite end or edge being journaled or pivotally supported in thecasing to swing to and from the saw so as to adapt the board tolong,-short and intermediate lengths of staple cotton, the board beingmoved and secured in any of its adjusted positions by a locking lever 19'ar- In the operation of the gin, the cotton passes to the gin saws 6where the seeds have been removed, and the trash, motes, leaves, dust,etc. are thrown ofi' in the chamber 7 by centrifugal action, the heavierpieces striking the guidevboard 8 and sliding to the mouth of thechute-9, where they are blown through this chute and the duct 10,

to the point of discharge, by that division cotton fiber adhering to thesaw teeth is blown ofi' by the air blast passing through the contractedopening 17 into the chute 13, from which it is swept to the condenser.The walls of the chutes and other portions of the gin with which thecotton contacts are preferably either lined with or formed by sheetmetal in order to lessen the friction so far as possible.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. In a cotton gin, a gin saw, a dust chamber adjoining the upperportion of the saw and having a downwardly and forwardly inclined rearwall, a chute leading from the dust chamber at the lower terminus ofsaid wall, a chute leading from a point adjacent to the saw below thedust chamber, an air supply duct discharging into the gin between thechutes, a downwardly and forwardly inclined deeotor arranged at thefront of the duct, and a dividing-member arranged between the chutes andforming in connection therewith air blast passages respectively directedto blowthe dust, metes, etc. from the chamber through the first1nentioned chute and blow the cotton adhering to the saw teeth into thelast-named chute.

2. In a cotton gin, a gin saw, a dust chamber-adjoining the upperportion of the saw, a Whipping-board at the bottom of the chamber andmounted to swing to and from the saw, a dust chute leading from thelower portion of the chamber at the back of the whipping-board, and anair blast to expel the dust, motes, etc. from the chute, 'passing inbetween the whipping-board and the bottom Wall of t-he chute.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witneses.

WILLIAM EDWARD COOKE.
